In the not-too-distant future, Los Angeles and the surrounding area has become a dystopian wasteland, heavily industrialized and overcrowded. Genetically engineered humanoid beings known as replicants are manufactured by the powerful Tyrell Corporation for use in dangerous off-world colonization. Retired police officer Rick Deckard (Harrison Ford), whose job was to track down replicants and assassinate them, is informed that four have come to Earth illegally. Called before his one-time superior (M. Emmett Walsh), Deckard is forced back into active duty to find and destroy the rogue replicants. Ridley Scott’s neo-noir classic initially polarized critics, but has since come to be regarded as one of the greatest sci-fi films of all time.
